Chapter 3 - Cross-linked chitosan and β-cyclodextrin as functional adsorbents in water treatment
(Elsevier, 2020-01-17)
In recent decades, the worldwide occurrence in water resources of various pollutants, such as toxic heavy metals, dyes, and pharmaceuticals, has raised increasing public attention about the inverse effects on human health ...
Separation and concentration of rare earth elements from wastewater using electrodialysis technology
(Elsevier, 2020-08-29)
Rare earth elements (REEs) including Scandium (Sc) are critical raw materials which are greatly needed in the advancement of many modern technologies. Due to the problems associated with the primary extraction of mining ...
MIL-101(Fe)/g-C3N4 for enhanced visible-light-driven photocatalysis toward simultaneous reduction of Cr(VI) and oxidation of bisphenol A in aqueous media
(Elsevier, 2020-04-21)
Heterostructured composites with an excellent photocatalytic activity have attracted increasing attention because of their great application in environmental remediation. Herein, a MIL-101(Fe)/g-C3N4 heterojunction was ...
A comparison of photolytic, photochemical and photocatalytic processes for disinfection of recirculation aquaculture systems (RAS) streams
(Elsevier, 2020-05-14)
The development of technologically advanced recirculation aquaculture systems (RAS) implies the reuse of water in a high recirculation rate (>90%). One of the most important phases for water management in RAS involves water ...
Phase separation of co-solvent promotes multiple bio-nanomaterials conversion from natural lignocellulose
(Elsevier, 2020-05-14)
Natural lignocellulose is supported by parallel bundles of cellulose (framework) and contains tightly interlaced hemicellulose and lignin. Based on the heterogeneous structure, an acid-catalyzed tetrahydrofuran–water ...
A new method for extraction of methanol-soluble brown carbon: Implications for investigation of its light absorption ability
(Elsevier, 2020-03-02)
As an important component of organic carbon (OC), brown carbon (BrC) plays a significant role in radiative forcing in the atmosphere. Water-insoluble OC (WIOC) generally has higher light absorption ability than water-soluble ...
Oxidation of 2,4-dichlorophenol in saline water by unactivated peroxymonosulfate: Mechanism, kinetics and implication for in situ chemical oxidation
(Elsevier, 2020-04-21)
Inorganic and organic pollutants present a hazard to surface and groundwater resources. Peroxymonosulfate (PMS, HSO5−) has received increasing attention for in situ chemical oxidation (ISCO) capable of remediating contaminated ...
Polyethylenimine-modified chitosan materials for the recovery of La(III) from leachates of bauxite residue
(Elsevier, 2020-02-03)
The separation and recovery of rare earth elements (REEs) from leachates of bauxite residue has attracted increasing attention. Yet, the characteristics of bauxite residue leachates (low pH, low concentration of REEs, and ...
pH-Independent Production of Hydroxyl Radical from Atomic H*-Mediated Electrocatalytic H2O2 Reduction: A Green Fenton Process without Byproducts
(ACS Publications, 2020-11-05)
Hydroxyl radical (•OH) can hydroxylate or dehydrogenate organics without forming extra products and is thereby expediently applied in extensive domains. Although it can be efficiently produced through single-electron ...
Compost: Potent biosorbent for the removal of heavy metals from industrial and landfill stormwater.
(Elsevier, 2020-07-13)
Stormwater can be contaminated with heavy metals and low-cost solutions are needed to treat large amounts of water. This study was conducted to determine the viability of compost as an adsorbent in Nordic conditions to ...
